Groundwater is pumped from a public-supply well and stored in a water tower for residents' use in Clayton, New Jersey. The well taps groundwater from the North Atlantic Coastal Plain aquifer.

Groundwater in the Atlantic and Gulf Coastal Plain aquifers is old—more than 21,300 years old in more than half of the wells sampled.

USGS scientists take samples of Lafferty Gulch surface water, which was analyzed for perchlorate and metals.

Sampling Lafferty Gulch surface water that was analyzed for perchlorate and metals on July 10, 2012. Water-quality sampling of groundwater and surface water was conducted during 2011-15 at Mount Rushmore National Memorial to characterize the occurrent of perchlorate and selected metals commonly associated with fireworks.
